pomp version 2.8 has been released to CRAN and is on its way to a mirror near you.
Important Changes
-
As promised with version 2.4.1.3, the default value of
tolin the particle-filtering algorithmspfilter,pmcmc,mif2, andbsmc2has been changed to zero. A warning continues to be issued iftolis set to anything other than 0. In a future release, the option to choose a nonzero tolerance will be removed entirely. This change is not backward compatible. If precise reproduction of old results is needed, set thetolparameter to the appropriate nonzero value. -
In traces and diagnostic plotting methods, the
nfailvariable (tracking numbers of filtering failures) has been dropped.
Minor change
- The Euler step size in
siris now adjustable by means of the argumentdelta.
